It recommends that doctors who suspect child abuse must tell the parents and the children about their concerns as soon as possible, as well as the action they intend to take.
GMC chief executive Niall Dickson said he hoped the new guidance will provide clarity in this ‘complex area of practice’.
He said: ‘We recognise that taking action to protect children from abuse can be challenging and distressing for everyone involved. We hope it will also help give doctors confidence to make these extremely difficult decisions.’
The consultation runs until 16 October 2011.
